Specification of Letters Patent No. 24,115, dated May 24, 1859.

To all 'whom it may concern:

Be it known that I, HENRY GLossnR, Vof the city, county, and State ofNew York, have invented certain new and useful Improvements inStereoscopic Cases; and I'do hereby declare that the following is afull, clear, and exact description of the same, reference being had tothe accompanying drawings, forming a part of this specification, inwhich- Figure 1 represents a vertical longitudinal section of astereoscopic base constructed according to my invention. Fig. 2 is aplan or top view of the same with the top removed. Fig. 3 is atransverse vertical section of the same.

Similar letters of reference in the three figures indicate correspondingparts.

This invention consists in arranging the case with a series of eyeglasses on the same side, and with one common reflector for all of them,so that a number of persons can have a look at the contents of the caseat one and the same time, and the picture frames are so arranged thatthey are brought before the different eye glasses by the action of oneand the same key or handle, a double motion being given to the same, onein the direction transversely through the case, and one in alongitudinal direction, the motion in both directions beingintermittent, so that sufficient time is allowed to the spectators tolook at each picture before it is replaced by another one.

To enable those skilled in the art to fully understand make and use myinvention I will proceed to describe its construction and operation.

A represents a case constructed of wood or any other suitable material,and in the usual form given to stereoscopic cases, with the onlyexception that the same is made considerably longer so as to give roomto several pairs of eye glasses, a, which are at such distances one fromthe other that several persons can conveniently look into the samewithout disturbing one another, and it must be remarked that theopenings, a, in Figs. 2 and 3, are to represent the double eye glasseseach, such as are usually attached to stereoscopic cases.

Inserted into the side of the case opposite to the eye glasses are theapertures, b, covered with a glass plate, b, which may be divided intoseveral panes to correspond to the number of eye glasses, or which maybe made out of one continuous plate placed over' the several apertures,b; and hinged to the top or lid, B, of the case is the reflector, C,which is long enough so that it serves as a common reflector-for theseveral eye glasses.

The picture frames, D, are arranged in sockets, c, which are attached toan endless belt, E, placed over rollers, Z and c, on one side of thecase, and a similar belt, E, with a corresponding number of sockets, c,is arranged on ro lers, CZ and e, on the other side of the case for thepurpose of taking off the picture frames after they have passed beforethe whole series of eye glasses. The belt, E, receives its motion bymeans of a handle or key, F, attached to an arbor, f, to the end ofwhich a cam, g, is attached which gears intov a worm-wheel, g, themotion of which is conveyed to a pinion, h, which is attached to thearbor, L, of the roller, e, and the shape of the cam, g, which resemblesa worm-screw with a left handed thread, is such that. the belt, F, ismoved on at certain intervals over a space equal to the distance fromone of the sockets, c, to the next adjoining one.

Arranged in a longitudinal direction through the entire'length of thecase, and extending from the belt, E, to the belt, E', is the channel,G, in which the picture frames slide along from one pair of eye glassesto the other; and the picture frames are arranged with rack teeth, z',at the lower edge, and a cam, y', which is attached to the arbor, f, andwhich is provided with a series of cogs running partly around itscircumference,

-serves to draw the picture frames from the sockets, c, into thechannel, G, and before the first pair of eye glasses. Another cam, j',similar to the cam, y', is arranged on an arbor, f', in such relation tothe channel, G, that the cogs, which extend partly around itscircumference in the same manner as the cogs on the cam, y', reachthrough a slot in the bottom of the channel. This cam serves to draw thepicture frames along in the channel, Gr, before the second pair of eyeglasses; and a similar cam, j, arranged in the same relation to thechannel, Gr, on an arbor f, brings the picture frames before the thirdpair of eye glasses and so on until the last cam, j, which is attachedto the arbor, f, pushes the picture frames out of the channel, Gr, intoone of the sockets, o', on the belt, E. The distance of these cams mustbein accordance with the length ofthe picture frames, so that the latterpass 'from one cam to the other.

Motion is conveyed to the several cams, j j j", by means of a lineshaft, H, which extends from one end'of the case tothe other one andparallel to the channel, G, and to which the gear wheels, k 7c 71: and16', are

fastened which mesh into similar wheels, Z Z Z Z", which are secured tothe arbors, f f `f and f", as clearly represented in Figs. `1 and 2. Thearbor, f", extends through, under the channel, Gr, :to t-he back Apartof the case, as clearly shown in Figs. 2 and 3; and a cam, g", issecured on its innerf end, similar, inevery respect, tothe cam, g, onthe arbor, f, with the only exception that `the thread which forms thiscam is a right handed screw-thread, and this cam gears into aworm-wheel, g, from which motion is conveyed to the roller, c,by meansofa pinion, la", which is secured to the arbor, `of the roller, c. Andas the screw thread which constitutesthe cam, g, is left handed, andthat one constituting the cam, g", right handed, both moving inthe samedirection, the motion conveyed to the belt, E, is in the direction ofarrow 1, and the motion of the belt, E, Vin the direction of arrow f2,and the picture frames, fed into the channel, G, from the sockets, c, ofthe belt,

E, are brought out to the 'front of the `case by the actionvof the belt,E.

The operation is as follows :MThe picture vframes `filled with thedesired pictures are arranged in the sockets, c, on the upper -side ofthe belt, E, and the machinery is set in motion by turning the key orhandle, F, in the direction from right to left, as indicated by arrow 3in Fig. 2. 'Bythe action of the cam, g, on the roller, c, `the sockets,c, are'drawn along inthe direction o'i'arrow l; and, whenever one of thesockets, @,comes in lline with the channel, Gr, the teeth of the cam, j,by gearing into the cogs, z', at Lthe lower end of the picture framecarry the same into `the channel, Gr, leaving them in proper positionfor the first ;pair `of eye glasses, and the teeth of the cam, j, are.in such relation to the cam, g, that the latter acts on the belt, E,while the icam, y', `is out of gear `with the Vpicture frame, and vthatithe belt, E, remains stationary during that space of time, in which the`cogs of the cam, j, act on Athe picture frames. VEach picture frame islett stationary before `the -iirst pair of eye glasses until by thecontinued motion `of lthe key, 'F,Tthe teeth of the second cam,

`glasses and at the same time a second frame is drawn into the channel,G, from the belt, E, by the action of the first cam, z', and in 'thismanner ithe picture frames are drawn into the channel and moved from onepair of eye glasses to the-otherby Ithe successi-ve `action yof thecams, j y" j, until the 'last cam', ?f", carries the same out Iinto oneof the sockets, c', which are brought Ito correspond with the channelGr, one' after the otherby theaction of the cam, gm, on `the roller, c.And as `these sockets move `in'the direction of arrow 2 the several 1picture frames are collected iin 'the front part o'f `one end of thecase in the same order in which they have been fed Iintorthe sockets, c,on the other end.

Nhat I claim as new and desire ftd-secure by Letters Patent is l. The`arrangement of two `or more `pairs of eye glasses on the same side ofia`stereoscopic case so that-several persons can look at the `pictures atone `and the Vsaine time, substantially in the m-anner herein specified.

Y 2. The picture Iframes, TD, arranged with cogs, z', or theirequivalent, at their flower edges in combination with the cams, 1 7' j1j and j, or theirequivalents, whereby the same are made to travel fromone vpair :of eye glasses to the other, substantially `as hereindescribed.

3. 'Giving a double motion =to 'the picture `frames, first in adirection transversely through fthe case by the action of theca'm,

0, or its equivalent on the endless belt, E,

and second, in a longitudinal direction iby the action of Ithe cams, j,substantially `as and for the Vpurpose set forth.

4. The arrangement Vand combination ontI the endless belts E and E','sto operate in relation to `the channel, Gr, substantially as and forthe purpose described.

5. Thecams, g and g", arranged :in combination with lthe teams, j `y"etc., or #their equivalents in .such a -manner that :they `produce thewithin described motion of the rpicture liframes at alternate intervals,lsubstan- -tially as and for the purpose specied.
